This repository is now archived, this book was published in 2019 and written in 2018. We have been trying to keep the repository up-to-date until now but eBPF had a tremendous evolution in the past 3 years. This does not mean that reading the book is a complete waste of your time now, many concepts are always the same: like how the bpf syscall works, the instruction set and things like how tracepoints, kprobes, uprobes, xdp and traffic control works. However, at this point, just updating the examples here is not enough anymore and many areas of the book would need to be rewritten to fit the new concepts, tools, libraries and the ecosystem around eBPF. A second edition is not yet planned (will update here if it ever happens).
